30 MPG combined is a surprisingly respectable figure for the 2018 Lexus LC 500h. It’s a grand touring coupe, a statement piece, and a showcase of Lexus’s engineering prowess. The hybrid drivetrain delivers commendable efficiency and enhances the driving experience with its instant torque and smooth power delivery. Buyers accepting this fuel economy prioritize style, comfort, and advanced technology over outright frugality at the pump.

City and highway performance

The EPA estimates for the 2018 Lexus LC 500h break down to 26 MPG in the city and 35 MPG on the highway. The city number reflects the benefits of the hybrid system’s ability to run on electric power at lower speeds and during frequent stops. The regenerative braking system captures energy typically lost during deceleration, further enhancing efficiency in urban environments. The highway figure demonstrates the car’s comfortable cruising ability, requiring less engine effort to maintain higher speeds. At 35 MPG, it surpasses many similarly-sized, conventionally-powered GT cars, and the effortless nature with which this vehicle achieves it truly impresses.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2018 Lexus LC 500h at $1,950. This figure is based on driving 15,000 miles per year and using the national average fuel price at the time of calculation. It’s an important benchmark for prospective buyers trying to estimate the long-term running costs of this luxury coupe. This is a helpful means of comparing the LC 500h to other vehicles in its class.

Real-world expectations

The EPA estimates provide a useful baseline, but real-world MPG figures will vary depending on driving habits, traffic conditions, and terrain. Drivers with a heavier foot or those who frequently engage in spirited driving should expect to see fuel economy closer to the low 20s. On the other hand, those who prioritize smooth acceleration, anticipate traffic flow, and maximize the use of the electric motor in city driving may approach or even exceed the EPA estimates. Variables like tire pressure and vehicle maintenance also play a role in achieving optimal fuel efficiently. Considering the LC 500h’s curb weight and the habits of its buyers, achieving the EPA numbers will require mindful driving.

How it compares

The 2018 Lexus LC 500h’s fuel economy places it ahead of many of its competitors. For example, the V8-powered LC 500 achieves only 19 MPG combined. Other comparable grand tourers, like the BMW 6 Series (no longer in production but the 640i Gran Coupe achieved around 24 MPG combined), also fall short. The Porsche 911, depending on the specific configuration, can achieve similar or slightly better fuel economy in some trims (the base 911 Carrera achieves around 21 MPG combined), but it lacks the hybrid powertrain and its accompanying smoothness. This fuel efficiency, while not the primary purchase driver, makes the LC 500h a relatively responsible choice in the luxury coupe segment. See LC MPG across all years for more historical data.

Tips to maximize efficiency

Use the LC 500h’s electric motor whenever possible. Gentle acceleration from a stop and maintaining a steady speed in stop-and-go traffic will allow the car to operate in electric mode for longer periods, significantly improving city fuel economy. Being aware of the car’s transition points between electric-only, hybrid assist, and gas engine operation can dramatically change fuel economy results, especially during short trips.

Anticipate traffic flow and avoid sudden acceleration or braking. The smoother you drive, the less demand you place on the engine, and the more efficiently the hybrid system can operate. Using the regenerative braking effectively will also help recharge the battery while minimizing energy loss. This driving style will require more attention than most drivers are accustomed to, but this is the way to achieve the highest MPGs.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, forcing the engine to work harder and reducing fuel economy. Check your tire pressure regularly and inflate them to the manufacturer’s recommended levels. Tire inflation pressure has an immediate affect on vehicle efficiency metrics.

Minimize unnecessary weight. Carrying extra cargo in the trunk adds to the vehicle’s overall weight, impacting fuel efficiency. Remove any items you don’t need to carry on a regular basis. Although the LC 500h’s buyers probably won’t use it for hauling, they should still remove unnecessary items and the weight that reduces fuel economy.
